After Palin wraps up, I race to the parking lot in search of departing Medicare-motor-scooter conservatives. I come upon an elderly couple, Janice and David Wheelock, who are fairly itching to share their views.

“I’m anti-spending and anti-government,” crows David, as scooter-bound Janice looks on. “The welfare state is out of control.”

Silence: Then Janice, a nice enough woman, it seems, slowly raises her hand, offering a faint smile, as if to say, You got me!

“Let me get this straight,” I say to David. “You’ve been picking up a check from the government for decades, as a tax assessor, and your wife is on Medicare. How can you complain about the welfare state?”

“Well,” he says, “there’s a lot of people on welfare who don’t deserve it. Too many people are living off the government.”

“But,” I protest, “you live off the government. And have been your whole life!”

“Yeah,” he says, “but I don’t make very much.” Vast forests have already been sacrificed to the public debate about the Tea Party: what it is, what it means, where it’s going. But after lengthy study of the phenomenon, I’ve concluded that the whole miserable narrative boils down to one stark fact: They’re full of shit. All of them. At the voter level, the Tea Party is a movement that purports to be furious about government spending — only the reality is that the vast majority of its members are former Bush supporters who yawned through two terms of record deficits and spent the past two electoral cycles frothing not about spending but about John Kerry’s medals and Barack Obama’s Sixties associations. The average Tea Partier is sincerely against government spending — with the exception of the money spent on them. In fact, their lack of embarrassment when it comes to collecting government largesse is key to understanding what this movement is all about — and nowhere do we see that dynamic as clearly as here in Kentucky, where Rand Paul is barreling toward the Senate with the aid of conservative icons like Palin.
